    • 摘要: 水稻在保障人类粮食安全中具有举足轻重的作用,当前中国水稻生产正面临由传统小规模生产向机械化、智能化和集约化的现代规模化生产方式转变,在此重要历史节点,该文回顾总结了新中国成立以来(1949—2024)机插稻、抛秧稻、直播稻和再生稻的机械化精简化栽培技术的发展历程,剖析各阶段的技术演进及发展成就,总结技术突破以及存在问题,并结合中国式现代化发展趋势,提出了未来机插稻、抛秧稻、直播稻和再生稻栽培机械化智慧化发展方向。机插稻要加强智能化集约化育秧、自主导航无人化机插与大田智慧肥水药管理等栽培技术创新,抛秧稻要加强标准化壮秧培育、高质量机械化智能化抛(摆)栽技术创新,直播稻要加强秸秆全量还田与高质量耕整播一次性全苗匀苗技术创新,再生稻要加强高再生力品种选配与轻碾压收获机械装备研发等技术创新。最后,概括性地展望未来水稻生产方式与发展方向,一是需将栽培农艺创新、智能农机具研制与相关现代信息技术深度融合,实现“农机农艺农智”科技融合创新;二是加强智慧绿色高产稻田建设、丰产优质高效协同形成模式与无人化栽培、智慧肥料与施用、智慧灌溉、智慧农药与无人化飞防等关键技术攻关,持续创新和改进水稻智慧栽培技术,创建适应中国不同生态区的水稻智慧生产工程技术体系;三是加强高素质人才、新农人、产业工匠等现代化智慧化农业生产复合型创新创业人才的培养。

       

      Abstract: Rice is one of the staple crops for national food security in China. The per-unit yield of the total rice production can be attributed to the yield potential of the rice varieties and the cultivation technologies over the past 75 years. Current agriculture has transformed from conventional small-scale farming to large-scale, intelligent, and intensive cultivation. In this study, a systematic review was presented to integrate the evolution of the mechanized and simplified cultivation techniques for the mechanical transplanting, seedling-throwing, direct seeding, and ratoon rice in China. After that, technological achievements were summarized to identify the existing challenges at each stage. Some insights were also aligned with the development trends of Chinese-style modernization. The potential future pathways were proposed for the mechanization and intelligence of the mechanical transplanting of rice, seedling-throwing, direct seeding, and ratoon rice. In mechanical transplanting rice, it was very necessary to enhance the cultivation techniques, such as the intelligent and intensive seedling raising, autonomous navigation transplanting with unmanned machines, as well as the fertilizer application, water, and pesticides management in a smart field. In seedling-throwing rice, it was important to strengthen the innovation of techniques, such as the standardized seedling cultivation, as well as the high-quality mechanized and intelligent seedling throwing and planting. In direct seeding rice, the techniques required to innovate such as the full straw returning to the field and one-time full seedling cultivation via tillage, preparation, and sowing. In ratoon rice, the innovative techniques were required for the high regenerative varieties and the light-impact harvesting machinery. Finally, the prospective production and future directions were outlined for rice cultivation. Firstly, the agronomic innovation, intelligent agricultural machinery, and modern information technologies were integrated to foster the synergistic technologies in the "agronomy, agricultural machinery, agricultural intelligence". Secondly, intensive research was promoted on the pivotal technologies, such as the smart, green, and high-yield paddy field, efficient synergy models for the yield and quality, unmanned farming, intelligent fertilization and precise application, smart irrigation systems, and unmanned aerial pesticide spraying. Thirdly, the high-caliber talents were required, including the new-generation farmers, industrial artisans, as well as the interdisciplinary innovative and entrepreneurial talents, in order to underpin the modern and intelligent agriculture.
